What is the role of MBS (methyl methacrylate butadiene styrene copolymer) impact modifier in CPVC (chlorinated polyvinyl chloride) pipes?
2024-11-08

1. Improve impact resistance performance:
-Enhance resilience:
MBS impact modifier can significantly improve the toughness of CPVC pipes. When subjected to impact, it can absorb and disperse energy through its own deformation, prevent brittle fracture of the pipe, and enable the pipe to better withstand various impact loads during transportation, installation, and use.
-Improve low-temperature impact resistance:
MBS impact modifier can effectively improve the low-temperature impact resistance of CPVC pipes, ensuring that the pipes maintain good toughness and impact resistance in low-temperature environments, and guaranteeing the safe operation of pipeline systems.
2. Promote the improvement of processing performance:
-Optimize plasticizing effect:
MBS impact modifier has good compatibility with CPVC, which can promote the plasticization of CPVC during processing, reduce plasticization temperature and time, and improve plasticization efficiency. This helps reduce energy consumption, improve production efficiency, and make the internal structure of the pipe more uniform, thereby improving the quality of the pipe.
-Improve melt flowability:
MBS impact modifier can improve the melt flowability of CPVC, making it easier for CPVC melt to flow in processing equipment such as extruders, thereby making pipe forming easier and reducing pipe defects caused by poor melt flowability, such as uneven wall thickness and surface defects.
